Struct exr::meta::attribute::Chromaticities

source ·
pub struct Chromaticities {
    pub red: Vec2<f32>,
    pub green: Vec2<f32>,
    pub blue: Vec2<f32>,
    pub white: Vec2<f32>,
}
Expand description

The color space of the pixels.

If a file doesn’t have a chromaticities attribute, display software should assume that the file’s primaries and the white point match Rec. ITU-R BT.709-3.

Fields§

§red: Vec2<f32>

“Red” location on the CIE XY chromaticity diagram.

§green: Vec2<f32>

“Green” location on the CIE XY chromaticity diagram.

§blue: Vec2<f32>

“Blue” location on the CIE XY chromaticity diagram.

§white: Vec2<f32>

“White” location on the CIE XY chromaticity diagram.

Implementations§

source§

impl Chromaticities

source
